Patent CA-2172989-A1 (CA)
Inventor: OLIVERA BALDOMERO M
IPC: C12N15/12
Filed: 1994-10-19
Abstract: The invention is directed to A-lineage conotoxin peptides, which are conotoxin peptides that have strong homology in the signal sequence and the 3'-untranslated region of the genes coding for these peptides to the sequences in the .alpha.-conotoxin peptides. The A-lineage conotoxin peptides include the .alpha.-conotoxin peptides, the .alpha.-conotoxin-like peptides and the -conotoxin peptides, described further below. The .alpha.-conotoxinpeptides generally share a "core" sequence motif. This core sequence is termed the .alpha.3/5 core and is represented as Cys-Cys-Xaa-Xaa-Xaa-Cys-Xaa-Xaa-Xaa-Xaa-Xaa-Cys (SEQ ID NO:1). The .alpha.-conotoxin-like peptides generally share a core sequence termed the .alpha.4/7 core and is represented as Cys-Cys-Xaa-Xaa-Xaa-Xaa-Cys-Xaa-Xaa-Xaa-Xaa-Xaa-Xaa-Xaa-Cys (SEQ ID NO:2). The -conotoxin peptides generally have a core sequence termed the 7/2/1/3 core and is represented as Cys-Cys-Xaa-Xaa-Xaa-Xaa-Xaa-Xaa-Xaa-Cys-Xaa-Xaa-Cys-Xaa-Cys-Xaa-Xaa-Xaa-Cys (SEQ ID NO:3).

Title: Control circuit and system for a switched reluctance machine and method of operating
Inventor: WEBSTER PAUL DONALD
IPC: H02P25/08
Filed: 1996-04-10
Abstract: A control  circuit  for a  switched reluctance  machine comprises a switch connected with the machine winding across a rectified ac power supply.  The switch controls the flow of current through the winding in a primary current path.   A silicon controlled rectifier and a capacitor are serially connected across the power supply and a diode is connected from a point between the winding and the switch to a point between the silicon controlled rectifier and the capacitor.  In  the steady state, the capacitor is charged each time the switch is opened.  The switch and the silicon controlled rectifier are actuated together so that the capacitor discharges through the silicon controlled rectifier and the winding until the capacitor  is  discharged  below  the  supply  voltage. Thereafter,  the  silicon  controlled  rectifier  ceases conduction and energy is drawn from the supply.   The circuit avoids the need for a dc link capacitor across the power supply to smooth the supply voltage.

Title: Process and device for controlling the carbon monoxide content of a furnace atmosphere for carburizing and carbonitriding metal workpieces
Inventor: ROGGATZ MAX
IPC: C23C8/22
Filed: 1996-04-17
Abstract: The invention concerns a process and a device for controlling the CO content of a furnace atmosphere for carburizing and carbonitriding metal workpieces in a furnace, whereby the furnace atmosphere is produced by direct feeding of a mixture consisting of an oxidizing agent and a hydrocarbonaceous fuel as well as perhaps ammonia into the furnace. To ensure a continuous and trouble-free operation of the installation without sooting of the furnace, it is proposed that the CO  content of the furnace atmosphere be ascertained and that a CO  forming substance is added when a freely adjustable minimum CO  content of the furnace atmosphere is attained. The device for carrying out this process has a CO analyzer 1 for ascertaining the CO content in the furnace atmosphere and a programmable CO  control 3 for actuating a valve 4 and, if applicable, a pump 5 in dependency on the CO content in the furnace atmosphere.

Title: Process for making an array of tapered photopolymerized waveguides
Inventor: FERM PAUL MICHAEL
IPC: G02B6/13
Filed: 1994-10-18
Abstract: The present invention is directed to a process for making an array of tapered photopolymerized waveguides. The tapered waveguides are useful as a display means in direct view devices and projection display devices. In step (a), a photomask is placed in substantial contact with a substrate wherein the photomask has opaque and transparent regions. In step (b), a substantially uniform thickness of photpolymerizable mixture is placed on the substrate so that the substrate is positioned between the photopolymerizable mixture and the photomask wherein (i) the photopolymerizable mixture comprises at least one reactive monomer and photoinitiator and (ii) the photoinitiator is present in an an amount sufficent to form a gradient of substantially collimated actinic radiation across the thickness of the photopolymerizable mixture during subsequent step (c). In step (c), while maintaining the photopolymerizable mixture and substrate in a substantially fixed plane relative to the substantially collimated actinic radiation, the photopolymerizable mixture is exposed through the transparent regions of the photomask to the substantially collimated actinic radiation for a time sufficent to form an array of tapered photopolymerizable waveguides wherein (i) the tapered end of each of the waveguides extends outward from the substrate, (ii) each of the waveguides has a light input surface adjacent the substrate and a light output surface distal from the light input surface, and (iii) the area of the light input surface of each of the waveguides is greater than the area of its light output surface. In step (d), the photomask and photopolymerizable mixture which was not substantially polymerized by the substantially collimated actinic radiation during step (c) are removed from the substrate.

Patent CA-2182446-A1 (CA)
Inventor: HARDEN WILLIAM H
IPC: F04C18/16
Filed: 1996-07-31
Abstract: An apparatus for electronically controlling the flow of low pressure gas to a compressor and preventing backflow from the compressor, the apparatus including a housing in fluid communication with the compressor, where the housing has a chamber, a housing inlet for receiving a low pressure gas, and a housing discharge port for flowing the low pressure gas to the compressor and through which backflow gas flows from the compressor.  A valve member having a contact end is movable within the chamber along a predetermined path.  The apparatus also includes a drive for moving an actuator along an axis.          The actuator has an extension with an end adapted to abut the contact end of the valve member to thereby move the valve member along the path toward the housing inlet.  The valve member is movable along the path and away from the inlet, when the actuator is retracted, by the flow of low pressure gas through the inlet.  Upon compressor shutdown, the back pressure moves the valve member to a substantially occluding position relative to the inlet position to prevent backflow from flowing outward from the compressor.

After peeling apart the temporary receiver and the cover sheet, exposed areas of the color layer attach to the temporary receiver and unexposed areas are removed with the cover sheet thereby forming a colored negative image on the temporary receiver sheet.  These steps are optionally repeated with another photosensitive element having a different colorant and adhere an image to the image previously produced on the temporary receiver sheet.  The temporary receiver sheet is laminated to a permanent receiver sheet via the images with heat and pressure.  The temporary receiver sheet is optionally removed.

IPC: H01S3/104
Filed: 1997-01-08
Abstract: A laser control system with multiple CPU's having shared memory on a common bus to provide high performance, relatively lost-cost, laser control. In the system disclosed, a first CPU which handles most, if not all, communication to and from the laser control system and which may communicate with one or more additional CPU's through the shared memory, so as to be capable of providing the software and operating commands to one or more additional processors on the common bus. A second processor is provided to control the intensity and repetition rate of a gas laser responsive to the program and commands made available thereto through the shared memory by the first processor. In addition, the second processor may directly respond to specific controls provided thereto to allow operation of the laser directly in response to control signals provided thereto from the outside, rather than based on parameters provided thereto by the first processor. Additional processors may beprovided on the common bus for other common, typically dedicated functions. The use of shared memory on a common bus for communication between processors allows automatic operation of a laser system through communication with only a single processor, simplifying system initialization and implementation of software updates. The controller is configured around a popular bus structure to make maximum use of commercially available board level subsystems to provide a highly versatile laser controller without requiring substantial and expensive special circuit board design and fabrication.
